MEANS FOR DRIVING SHUTTLES OF LOOMS.

SPECIFICATION forming part of Letters Patent No. 703,419, dated July 1, 1902..

Application filed October 12, 1800. Serial No. 32,876- (No model.)

To aZZ whom it may concern:

Be it known that I, J oHN HOUSTON, a subject of the Queen of Great Britain, and a resident of Sunderland, in the county of Durham, England, have invented certain new and useful Improvements in Means for Driving Looms, (for which I have applied for a patent in Great Britain, No. 21,842, dated October 31, 1899,) of which the following is a full, clear, and exact specification.

This invention relates to driving or motoring looms and other machinery used in textile manufacturing and the motoring or giving motion to the shuttles thereof.

In carrying out my invention I supply a motor which is directly connected to the shuttle-throwing mechanism and is actuated by compressed air conveyed thereto from a convenient outside source.

Referring to the annexed drawings, Figure l is a side elevation showing my invention; Fig. 2, a plan view of same.

a is a pipe which conveys the compressed air, being suitably connected to what I term the valve-box b, so as to allow for the necessary play or movement. The rod 0 is controlled by the spring (1 and is moved in the direction of the arrow 1, when it allows the compressed air to operate upon a piston in the cylinder 6 and throw the shuttle f, as shown by the dotted lines in Fig. 2.

g is a rod provided with a cam-surface h, adapted to engage upon the roller 2', carried upon the rod 0, j being the spring for controlling the movement of this rod 9, the rod 0 being operated by the rod 9 in a vertical direction, and the operation of the rod 9 by the hereinafter-described mechanism is so timed in relation to the reciprocal motion of the part carryingthe compressed-air cylinder that the'rod c is vertically operated when it comes into lateral position. (Shown in Fig. 1.) The lever his pivoted at Z to the support m or frame of the machine, and the operation of the pin Z upon the wheel 0, which is in gear with the wheel p on the driving-shaft q, will cause the lever is to be moved into the position which will raise the rod 0 and through the medium of the valve carried in the valvebox I) will allow the compressed air to enter the cylinder 0 and act upon the piston-rod 1", thus throwing the shuttle f in the direction of the arrow 2. Upon the shuttle being thrown again from the other side of the machine avcertain cushioning action may be exerted or the parts may be so arranged that the parts throwing the shuttle may return to their operative position through the action of the shuttle striking them or' by pneumatically placing them in the required position.

I'Iaving thus described my invention, what I claim, and desire to secure by Letters Patout, is-

In looms and other textile machinery, a cyl inder piston and piston-rod attached to the desired part of the machine and adapted to be operated by compressed air, said pistonrod having a projection for throwing the shuttle, a valve controlling the admission of compressed air to the cylinder aforesaid, a valverod carrying said valve and having a roller or Wheel attached thereto, a cam carried by an intermediate rod and engaging with the roller or wheel aforesaid, a pivoted lever engaging-with the end of said intermediate rod, a projection carried by one of a train of gear wheels driven from the main shaft and adapted to periodically engage with and operate the pivoted lever aforesaid, substantially as described'and illustrated herein and for the purpose set forth. I I In. testimony that I claim the foregoing I have hereunto set my hand this 16th day of August, 1900 JOHN HOUSTON Witnesses:
